Letter http://www.ibiblio.org/eldritch/nh/hb12.html to Horatio Bridge (15 March 1851)
Context: How slowly I have made my way in life! How much is still to be done! How little worth — outwardly speaking — is all that I have achieved! The bubble reputation is as much a bubble in literature as in war, and I should not be one whit the happier if mine were world-wide and time-long than I was when nobody but yourself had faith in me.
The only sensible ends of literature are, first, the pleasurable toil of writing; second, the gratification of one's family and friends; and, lastly, the solid cash.

To make a man confess a loving God you burn him!
The Heretic (1968)
